Why no use sync rather than async for NFS storage?
Hello,
All cloudstack documentation prepares the NFS share using async, why not use sync for better data protection?
Has anyone used NFS shares with sync? what would be the drawbacks if any?
Thanks for your valuable responses.

Just created CLOUDSTACK-6166 to change this, or at least get a good reason for why folks think it’s OK.

Interesting - hadn’t noticed that.
Async is generally faster, at the risk of data loss as the client isn’t guaranteed data write on the server. Not something I’d run in production.
